Just install Qt™, KF5 and Konqueror, and from your favorite
window manager, launch Konqueror. It should work just fine, but if it
doesn't (KDE developers don't test that case often), report it to http://bugs.kde.org and try running
kdeinit before running Konqueror; it usually
helps.

12.2.

Where does Konqueror keep all its configuration
data?

Generally in the qtpaths --paths GenericDataLocation folder (this may
be ~/.local/share on your system, depending on how Konqueror
was installed). Don't alter these files unless you really know what you are
doing.

Your bookmarks are held in konqueror/bookmarks.xml

Cookies are held in kcookiejar/cookies

Your history, as used for the auto-completion feature, is in
konq_history in the folder
qtpaths --paths GenericConfigLocation.

In the folder qtpaths --paths GenericConfigLocation the file
konquerorrc holds a whole lot of general configuration
settings.

Any folder specific view settings are put into .directory files in the individual
folders.

12.3.

How do I clear out the history file?

There are two “histories”:

One is used for text completion in the Location Toolbar text entry
box. To clear this right click on the text entry
box and select Clear History
.

The other is the log of visited locations. Select Show History
in the menu Go and right click on an entry and choose
Remove Entry (Del) to remove just that entry or
Clear History to delete all
entries.

Note

You can also use the application Sweeper from
the kdeutils module which allows you to clean up cookies, favicons, web history and cache,
form completion entries and cache policies of visited websites.

12.4.

How do I enable, disable or clear the browser
cache?

If you select Web Browsing → Cache in the dialog launched by selecting
Settings → Configure Konqueror...
, you will be presented with a dialog box that lets
you disable the cache, clear it or set its size, and change the caching
policy.

12.5.

How can I change the timeout values used by Konqueror
when web browsing?

In the System Settings category Network
on the Settings → Connection Preferences page.

12.6.

How do I set my “home” page - the page loaded
on startup?

Konqueror has a Home Folder used in file manager mode
and a Home Page used in browser mode.
